A contact assembly for an electrical connector includes a holder and multiple ground contacts and signal contacts. The ground contacts and signal contacts are held by the holder along an outer side of the holder. The ground contacts and the signal contacts each have a mating segment proximate to a front end of the holder and a terminating segment proximate to a rear end of the holder. Ground contacts nearest to each other define a contact spacing therebetween. The nearest ground contacts are mechanically connected by a bridge member that connects the mating segments of the nearest ground contacts to electrically common the ground contacts. At least one signal contact is disposed in the contact spacing between the nearest ground contacts. The ground contacts provide electrical shielding between the signal contacts that are in different contact spacings.
